I'd suggest 2 courses of action for the OP. First buy some ammo and learn the art of aiming. Then he should stop watching films on TV where the actors practice the art of spray and pray. Pretty simple, really. If someone is shooting at your or into the crowd, take careful aim. If the pressure is too much and you can't aim, don't waste the ammo shooting at the bad guy. You'll just give away your position and he may identify you as a threat. I'm guessing he's a better shot.
